Abstract

The bearing has internal and external bodies whose radial annular groove borders a bearing ring. A rolling body is retained in housings (6) of a retention cage (5). Bridges (8) axially extend on an internal face of a radial crown (7) of the cage. The rolling bodies maintained in the housings are arranged on side faces (9, 10) of the bridges and in slipping contact with each other. A free edge (13) of the radial crown is arranged in the radial annular groove such that the crown forms axial abutment for the rolling bodies.
